Specification of Letters Patent.

. Patented July 22, 1919.

Application filed .Tune 20, 1918. Serial No. 241,029.

To all whom it may concern:

Be it known that I, CLYDE M. NYE, a citizen of the United States,residing at Emmett, in the county of Gem and State of 'Idaho, haveinvented a new and useful" Switch, of which the following is a.specification.

The subject of this invention is a switch such as is used for making andbreaking an electric circuit. 7

The main object of'the invention is the provision of means fordisplaying a signal on an automobile when the same is to 0e reversed orbacked.

Another object of the invention is the provision of means operated bythe reversing lever for displaying a signa I,

- The invention also contemplates generally improving theconstructionand enhancing the utility of electric switches.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed can be made within thescope of what is claimed without departing from the spirit of theinvention.

A practical embodiment of the invention is shown in the accompanyingdrawing, 'wherein: J

Figure 1 is a view in side elevation of a sw1tch constructed inaccordance with the mventlon, shown applied, the position assumed by thereversing lever when in reverse being shown in dotted lines;

Fig. 2 is an enlarged view in side eleva- 0 tion of the switch;

Fig. 3 is a plan view of the same; 'g. 4 is a rear end elevation; Fig. 5is a fragmentary front end elevation showing the 'mountmg of the switch4 4 elements;

Fi 6 is a diagrammatic view of the switc and its circuit.

Referring to of reference The usual plate is shown at 1, which isfastened to the floor of an automobile, as indicated, and which issuitably slotted to allow roper play of the control lever 2. Secure tothe floor of the automobile; im-

' mediately in front of the plate 1, is the the drawing by numeralsscrews 16 or otherwise, the insula minals 17,0n the forward ends ofwhich 0 switch which forms the subject of this invention.

The switch consists of a base plate 3, the forward end of which isupturned, as at 1. Upon this plate 3 is secured, by screws or otherwise,an arch 5 which is positioned adjacent the rear end of the plate, andwhich extends transversely of the plate. Secured uponthe top of the arch5 is a horizontally disposed bar 6 which extends longitudinally of theswitch structure, and which has its forward end 7 downwardly bent, andthis end is positioned to the rear of and in spaced relation to theupturned end 4 of the plate' 3. The ends 4 and 7 are apertured toreceive the threaded end of a horizontally disposed rod 8 which is heldin place in said apertures bythe clamping nuts 8 and which also extendslongitudinally of the switch. The lower end of the bent end 7 isapertured to receive thehook endmf a retractile spring 9.

' The rear end of the bar 6 is forked and the fork portions apertured toreceive a pin 10' which serves to fulcrum a lever 11 on the bar. Thedownwardly extendin arm of .the lever 11 has the rear end of tieretractile spring 9 fastened thereto. This spring serves to draw thelower end of the lever 11 forwardly and the movement of the lower end orarm of the lever in such direction is limited by the rear end of-the rod8, against which the'lever strikes.

Secured to the. upper arm of the lever 11 by a bolt 12 and nuts 12'which are threaded thereon, is a wedge block 13, while on the rearwardlyprojecting end of the bolt 12 is secured a fork 14, which is adapted tostraddle the lever 2 when the lever is thrown to reverse ]position, andengage Y e t e the lever so that the ver 2 may rock lever 11 against thetension of the sp 9, and so throw the wedge block 13 forwardly toseparate the resilient leaves of the switch, as will be set forth.

A support 15 is secured toand rises from [the bar 6, near the forwardend of the-1781.11,

and to this support are attached, b

ter-

are the upstanding connector ends 18. The terminals 17 are of leafformation and be-' tween these terminals and insulated from them andfrom the support 15 are the resilieht leaf switch members 20 which arein 0 electrical connection through strip 20. Circuit wires 19 areconnected to the connector ends 18 for the purpose of conducting currentfrom a suitable source of electrical supply to the switch.

The circuit wire 19 which leads from one terminal 17 is connected to onepole of a suitable source of electrical supply, such as the battery 21,groundedas at 22. The wire 19 connected to the other terminal 17 isgrounded, as at 24, and in this, portion of the circuit are in terposeda lamp 23, which is situated at the rear end of the automobile, and theusual light circuit switch 25.

As will be understood, when the switch 25 is closed, thedevice is incondition for operation. When the lever 2 is thrown to. reverse it comesinto contact with'the fork 14C and rocks the lever 11, thereby, throwingthe Wedge block 13 between the forward ends of the resilient. leafmembers 20, and causin them to contact the terminals 17 This wil placethe terminals 17 in electrical contact through the members 20 and thebridging strip 20, and thus complete the circuit from the battery 21through the lamp 23. This causes the lamp to light and so notifies oneto the rear of the automobile that the same 1s reversed. I

Having thus described the invention, what is claimed as new and soughtby Letters Patent, is z,

1. A switch, including a base plate, an

arch secured to and rising from the base 7 a bridging the other pole ofwhich is plate, a horizontally disposed bar secured to the arch, .alever fulcrumed at one end of the bar, a. wedge block carried bth'elever, resilient means for holding the lever in normal position, asupport on the bar, terminals securedto and insulated from the support,and

resilient members separated to contact and bridge the terminals when thewedge block is swung between the members 'by' the rocking of the lever,and means for rocking the lever.

2. A. switch including a base plate having an upturned end, an archsecured to the base plate, a bar attached to the arch and having adownturned end in spaced relation to the upturned end of the base plate,arod adjustably secured to the said ends and forming a stop, a leverfulcrumed on one end of the bar, resilient means for normally holdingthe lever against the rod, a wedge block carried by the lever, terminalsmounted on the bar and insulated therefrom and from each other, aresilient bridging member adapted for separation tocontact theterminals, and means for rocking the lever to swing the wedge blockbetween the bridgingmember. I In testimony that I claim the foregoing asmy own, I have in the presence of two Witnesses.
